Also known as a dorm rat. A student that for whatever reason, wants no part of the greek system. They oftentimes sit alone in their dorms on weekends wondering whats going on in the outside world. They have a distinct unfounded hostility toward Greeks, but never hesitate to leach off of them, such as drinking their beer, or attending parties, from which they always end up going home alone. Many of them get all of their information on Greek life from TV and movies, they never bother to do any actual research. According to them, Greeks are "losers who have to pay for their friends." It never occured to them that one of their favorite celebrities is very likely a greek. It never occured to them that a "frat boy" could someday turn out to be, say, some of the greatest athletes/coaches of all time(Michael Jordan, Shaq, Karl Malone, Wilt Chamberlain, Orel Hershiser, Terry Bradshaw, John Elway, Jerry Rice, Emmit Smith, Jackie Robinson, Hank Aaron, Pat Riley, Phil Jackson, Larry Brown, Mike Ditka, Tiger Woods, Jesse Owen, Troy Aikman, Lou Gehrig, just to name a few), some of the most famous actors/entertainers(Elvis Presley, Johnny Carson, David Letterman, James Caan, Burt Reynolds, Bob Hope, Brad Pitt, Matt Groening, Steven Spielberg, Warren Beaty, Tom Selleck, Ron Jeremy, Paul Newman, Merv Griffin, Danny Thomas, James Dean, Harrison Ford, John Wayne, just to name a few), (Martin Luther King Jr., Rev. Jesse Jackon, Nelson Mandela, 85% of US Supreme Court Justices, 76% of the Nations senators, all but two US presidents since 1825), a famous astronaut(everybody on the Apollo 11 crew), a famous business owner(43 of the 50 largest corporations in the nation are headed by "frat boys"), or even their mommy and daddy's boss. According to studies, only about half of GDI's end up graduating college, as opposed to 71% of Greeks.

(God Damn Independent). A college student who is not an active or a pledge to a particular sorority or fraternity. The GDI has either chosen to not affiliate with the greeks or maybe rushed and did not pledge. GDI's tend to have a reputation of being dorm rats but some GDIs are cool and have some greek friends. Just depends on the particular GDI. Being titled a GDI should not judge who someone is, its just a decision.

Acronym for "God Damn Independent," often used in a derogatory way to refer to a college student who chooses not to join any sorority or fraternity.

Seems to be used in a derogatory way the most by people affiliated with the 'Greek' system because they do not realize that 'independent' really isn't even an insult. Typical brainless, follow-the-crowd, frat people. Damn, frats and sororities are like cults. People go in fine and come out brainwashed, dumb, and/or slutty. IF they ever come out.

Vic: What's your title?

Sam: What?

Vic: You know, what frat are you in?

Sam: Oh, I'm a GDI.

Vic: Wow, I really think you should go Greek.

Sam: You know, they're not even really Greek. They just jacked the Greek letters and twisted them to use in their half-assed, drunk-partying organizations. I only rushed for the free food. You'd have to pay me to join one.

Vic: Why don't you join?

Sam: Um, it costs money I can't afford to waste, I can make friends on my own time, I don't really want to be saddled with people I don't like, I don't like to do pointless shit, and I don't like how they always call each other 'big' and 'little.' It's hella annoying. Oh, and I don't really like to conform.
